betta often pale when stressed, like when being moved a lot or introduced to a new environment. Give him a day or two to settle in and he should start coloring up in no time. It's also common for betta to refuse food in the first day or two, so if he's one of those, don't worry right away. Just keep an eye on him, learn his habits and give him time to get settled. And post a better picture when he's set up, I wanna seeeee!

Not sure how common it is, but most of the red colored fry of my spawn have the ability to white out when stressed. Even their fins can turn from red to clear. It does turn back, and the one that i shipped that has been received took a couple days to turn back.

This betta was from a small aquarium store with just the owner working there. He said he only feeds them bloodworms.... so, I figured I'd feed him that for a couple days until I'm sure he has settled in and then change him to the pellets... don't want to stress him with too many changes all at the same time.

Just bloodworms? Yeah, not what most people around here would recommend, I think. If you're going to feed him bloodworms, I would go with frozen, as freeze dried can cause tummy problems. It sounds like you have a solid plan, sneak a pellet in there and see how he reacts. Once he's on the pellets, a bloodworm snack is fine once a week or so.

One more thing you might want to keep in mind.. pet stores, even the little ones, tend to have much better lighting then our homes and fish tank lights. He might color up but look a bit different then he did in the store just because your lights aren't the same.

He'll colour back up. My boy used to go white in the face, and his fins would turn brownish clear every time I cupped him. Now he's in a cycled tank so we don't have that problem. Claustrophobic betta lol.
